Sonalert® SC628ANP
The Mallory Sonalert SC628ANP Audible Alarm is a high-output, panel-mounted electronic sounder designed to provide a distinctive, fast-pulsing audible warning for electrical equipment and monitoring systems.
Operating across a versatile 6–28V AC/DC range, the SC628ANP generates a fast-pulse alarm signal at 2–10 pulses per second, with a typical sound output of 88–101 dB(A) measured at 2 feet. Its low current draw of 4–30 mA makes it suitable for integration into control panels, equipment monitoring circuits, and alarm systems where clear audible notification is required.
The alarm features a rugged black 6/6 nylon housing, threaded panel-mount construction, and an included knurled mounting nut. Its operating temperature range of -30°C to +65°C supports installations in demanding equipment environments.
For marine electrical applications, the SC628ANP can serve as an audible notification device in vessel monitoring panels, equipment fault indication systems, and machinery alarm circuits, provided the installation meets applicable electrical and environmental requirements.
